Hinge structure

ABSTRACT

A hinge structure which can be used on a storm door or window combines a mounting frame for the door or window and a hinge leaf attachable to the door or window and having a knuckle portion registrable in a cutaway section of the frame which is of a configuration forming a registering knuckle in which pintles positioned in the knuckle of the hinge leaf can be engaged. A coil spring is positioned between the pintles with its opposite ends secured thereto. The registering knuckle portion of the hinge leaf has a large cutaway area exposing the spring therein so it can be manually engaged and temporarily moved out of the knuckle to move the pintles into the ends of the knuckle and permit the hinge leaf to be positioned in the cutaway section of the frame. Release of the spring moves the pintles into the knuckle configuration of the frame to complete the hinge structure.

FIG. I

HINGE STRUCTURE 7 This is a continuation-in-part of my application, Ser.

No. 454,013, filed Mar. 22, 1974.

BACKGROUND OF THE INVENTION 1. Field of the Invention I H 1 Thisinvention relates to hinge structures as usedfor example with door andwindow frames and doors and windows hingedly mounted therein and whereinthe frames and doors and windows are generally formed with aluminumextrusions. V

2. Description of the Prior Art Prior structures of this type haveemployed -doo r frames with hinge forming components and hinge leavesregistrable therewith and springs positioning pintles in operativerelation thereto, as for examplein US. Pat. No. 2,903,735. Still otherarrangements of spring urged pintles in hinge constructions may be seenin US. Pat. Nos. 3,375,546, 367l,99 8' and 3,673,636.

This invention is a substantial improvement over the prior artstructures as for example that set for th in US. Pat. No. 2,903,735 inthat the hinge leaf, the pintles and the spring which will hold them inoperativerelation between the hinge leaf and the matching configurationsin the door or window frame are pre-asseinbled and arranged to bemanually moved to temporary inoperative position when the door or windowis actually installed in the frame at the point of use.

SUMMARY OF THE INVENTION A hinge structure comprises a hinge leaf havinga pintle receiving knuckle thereon, a pair of pintles therein, a coilspring positioned between the pintles and a large cutaway area in theknuckle so that a portion of the coil spring can be temporarily movedout of the knuckle to re-position the pintles within the knuckle wherebythe hinge leaf may be moved into a cutaway section of a pintle receivingconfiguration in a mounting frame so that release of the spring permitsit to assume its normal position and move the pintles into hingedrelation between the hinge leaf and the pintle receiving configurationof the frame.

DESCRIPTION OF THE DRAWINGS FIG. 1 is a plan view of a hinge leaf withparts broken away and parts in cross section and illustrating pintlesdisposed in the knuckle portion thereof and spring means engaging thepintles, broken lines illustrate a position to which the spring may bemoved and temporarily held in inoperative relation;

FIG. 2 is an end elevation of the hinge leaf seen in FIG. 1, brokenlines illustrate the spring moved from its normal position; and

FIG. 3 is a horizontal cross section through a construction including adoor frame and a door and illustrating the hinge leaf of FIG. 1 inoperative position in a cut-out section of the door frame.

DESCRIPTION OF THE PREFERRED EMBODIMENT In its simplest form the hingestructure disclosed herein consists of a hinge leaf 10 apertured at 11so that it can be attached to a door or window frame or the like andhaving one longitudinal edge thereof formed in a continuous crosssectionally circular knuckle 12 with a portion of the knuckle 12 betweenthe ends thereof .beingcutawayas at 13 to'form" an elongated, wideaccess opening therein. A pair of pintles 14 are slidably positioned inthe opposite end portions of the knuckle IZ andare partiallyretainedwithin the knuckle 12 by small dimples ,15 formed inthe walls of theknuckle 12 adjacent the endsthereof. Each'of the pintles 14 has acentral portion, an outerend extension 16 of smaller diameter than the,central portion and a tapered inner end portion 17. The tapered innerend portions 17 of thepintles are frictionally engaged in the ends of acoil spring 18. V I s The pintles. 14 are thus normally held in theposition shown in solid lines in FIGS. 1 and 2 of the drawings by thecoil spring 18 which is normally on an axial center line therebetween. gn,

In FIGS 1 and 2 of the drawings the coil spring18 is illustrated in itsnormal straightlin e position in the knuckle 12 of the'hinge leaf '10and broken lines show it temporarily held in bowed position as it may bemoved'by the thumb of awor'kman holding the spring 18 so as'to partiallyretract the; pintles 14 to enable the hinge leaf 10 and the pintles 14to be positioned in a cutaway section of a knuckle configurationin 'aframe.

By referring'n'ow to FIG. 3 of the drawingspthe complete hinge structureof the invention may be'seen to include the hinge leaf 10 heretoforedescribed and a mounting'fram'e'19 which includes acontinuous'longitudinally extending, cross s'ectionallycircular"pintle'receiving knuckle configuration 20. Two or more areas ofthe pintles receiving knuckle configuration 20 are cutaway, the lengthof the cutaway areas being slightly greater than the length of theknuckle 12 of the hinge leaf l0 heretofore described so that the knuckle12 on the hinge leaf 10 may be positioned in the cutaway area of theframe 19. When the knuckle 12 of the hinge leaf 10 is so positioned, theouter end extensions 16 of the pintles 14 will move outwardly of theends of the knuckle l2 and into the pintle receiving knuckleconfiguration 20 of the mounting frame 19 as urged by the coil spring 18when the same is permitted to assume its normal position.

Bushings may be positioned between the pintle receiving knuckleconfiguration 20 and the ends of the knuckle 12 in the hinge leaf 10 ifdesired as will occur to those skilled in the art.

It will thus be seen that the hinge structure disclosed herein providesfor the pre-assembly of the hinge leaf 10 to include the pintles 14 inthe knuckle 12 thereof and the coil spring 18 therebetween with thesmall dimples 15 in the knuckle 12 holding the pintles 14 in the knuckle12 to insure a complete and useable hinge leaf assembly which may beattached as by fasteners 21 to a door or a window 22 as seen in FIG. 3of the drawmgs.

Those skilled in the art will observe that when a door and a door frameor a window or window frame are installed in a building, a frame such asthe mounting frame 19 disclosed herein is cut to fit the opening andinstalled therein by fasteners all as known in the art. Each assembliedhinge leaf 10 to be used may then be positioned in the respectivecutaway portion of the pintle receiving knuckle configuration 20 of themounting frame 19 when the spring 18 is partially withdrawn from theknuckle 12 by the workman so as to permit the pintles 14 to move intothe ends of the knuckle 12. Release of the spring 18 positions the endextensions 16 of the pintles 14 in the pintle receiving knuckleconfiguration 20 of the frame 19 to movably attach the hinge 3 leaf lthereto. The door or window may then be attached to the hinge leaf 10.

If desired, the procedure may be reversed with the hinge leaf attachedto the door or window at the proper locations thereon and thenpositioned in registry with the cutaway section of the pintle receivingconfiguration of the mounting frame 19.

The above-described structure provides a relatively easy and fastassembly of doors and windows in mounting frames at their point of useand is versatile in that it can be used on windows and doors of varioussizes and shapes.

Although but one embodiment of the present invention has beenillustrated and described, it will be apparent to those skilled in theart that various changes and modifications may be made therein withoutdeparting from the spirit of the invention.
